Given numbers are 182,428,552,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 182,428,552,680 is 456860040.
Find LCM of 182,428,552,680 with Prime Factorization
| 2 | 182, 428, 552, 680 |
| 2 | 91, 214, 276, 340 |
| 2 | 91, 107, 138, 170 |
| 91, 107, 69, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 91 x 107 x 69 x 85 = 456860040
Therefore, the lowest common multiple of 182,428,552,680 is 456860040.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
182 x 428 x 552 x 680 = 29239042560
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
182 : 1, 2, 7, 13, 14, 26, 91, 182
428 : 1, 2, 4, 107, 214, 428
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 182,428,552,680, is 2.
Now, the common factors can be found like this.
182:2x 7x 13
428:2x 2x 107
552:2x 2x 2x 3x 23
680:2x 2x 2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2 = 32
Therefore, the value for common factors is 32.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 29239042560/(2x32)
LCM = 29239042560/64
LCM = 456860040
Thus, we can understand that the LCM of 182,428,552,680 is 456860040.
